Silicone compositions for personal care products and method for making

ABSTRACT

A composition and method for making a silicone composition is provided which comprises at least one polysiloxane or silicone resin, at least one linker, and at least one molecular hook wherein the molecular hook comprises a heterocyclic trimethylpyrimidinium compound.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to compositions for personal care products. More particularly, the present invention relates to silicone compositions which achieve conditioning benefits in hair care products.

[0002] Silicones are widely used in hair care products due to the conditioning benefit that they impart to hair. By modern day technology, the silicone is deposited on hair during the application process but is held only by weak physical forces, such as hydrogen bonding or van der Waals interactions. Generally, conditioning benefits are attributed to the deposition of high molecular weight, high viscosity fluids and gums which can weigh down the hair. Because the interactive forces are weak, the benefits of silicone by deposition are short lived. Beneficial conditioning effects can also be caused by treating hair with silanol capped amino-functionalized silicones. These can undergo condensation cure reactions on hair to form somewhat durable films.

[0003] It is widely known by those skilled in the art that covalent bonding is one key to “permanent” hair treatment. Processes which alter the structure of the hair, such as permanent wave and color treatment methods, do provide longer lasting effects. These processes include glycolate reduction and peroxide reoxidation. A significant disadvantage of these processes is that they are very damaging to hair and can only be carried out infrequently.

[0004] Gough et al. in U.S. Pat. Nos. 5,523,080 and 5,525,332 describe the synthesis of silicone-azlactone polymers which exhibit covalent bonding and “permanent” conditioning benefit. Gough et al. discuss incorporating an azlactone-functionalized copolymer which consists of vinylazlactone and methacryloyl polydimethylsiloxane monomers into a silicone-active group-hair structure. The hair treatment using the silicone-azlactone polymers does not consist of the steps of reduction with a glycolate or reoxidation with peroxide.

[0005] It is desirable to produce silicone compositions which can be used to treat damaged hair and provide durable benefits. Thus, silicone products are constantly being sought which can both covalently bond to hair as well as impart hair care benefits appreciated by consumers.

[0023] Hydrosilylation is typically accomplished in the presence of a suitable hydrosilylation catalyst. The catalysts preferred for use with these compositions are described in U.S. Pat. Nos. 3,715,334; 3,775,452; and 3,814,730 to Karstedt. Additional background concerning the art may be found at J. L. Spier, “Homogeneous Catalysis of Hydrosilation by Transition Metals, in Advances in Organometallic Chemistry, volume 17, pages 407 through 447, F. G. A. Stone and R. West editors, published by the Academic Press (New York, 1979). A preferred catalyst contains platinum. Persons skilled in the art can easily determine an effective amount of platinum catalyst. Generally, an effective amount is in a range between about 0.1 parts per million and about 50 parts per million of the total silicone composition composition.

[0024] The organohydrogen silicone compounds that are the precursors to the compounds of the present invention may be prepared by the process disclosed in U.S. Pat. No. 5,420,221. The '221 patent discloses the redistribution of polydimethylsiloxane polymers with organohydrogen silicone polymers and optionally, added chain stopper, to provide a silicone with randomly-distributed hydride groups using a Lewis acid catalyst, preferably a phosphonitrilic compound.

[0025] Synthesis of the polysiloxane or silicone resin may also be performed by other method known to those skilled in the art, for example, the hydrosilylation of a monomer such as methyldichlorosilane could be followed by co-hydrolysis with the appropriate dialkyldichlorosilane and optionally, chlorotrimethylsilane.

[0026] It is to be noted that as pure compounds, the subscripts describing the organohydrogen siloxane precursor and the hydrosilylation adduct of the present invention are integers as required by the rules of chemical stoichiometry. The subscripts will assume non-integral values for mixtures of compounds that are described by these formulas. The restrictions on the subscripts heretofore described for the stoichiometric subscripts of these compounds are for the pure compounds, not the mixtures.

[0034] The linker comprises any C₁-C₁₀₀ alkyl, aryl, or alkylaryl group where the C₁₋₁₀₀ group can be interrupted by or substituted with aromatic groups or aromatic-containing groups. The C₁₋₁₀₀ group may also contain one or more heteroatoms such as O, N, or S. Furthermore, the C₁₋₁₀₀ group may be unsubstituted or substituted with heteroatoms such as halogen. Typically, the linker has the formulas (IX) through (XV):

[0035] where

[0036] r is in a range between about 1 and about 10, preferably 2 or 3;

[0037] s is in a range between about 0 and about 100, preferably 4 to 20;

[0040] v is in a range between about 1 and about 10, preferably 2 or 3;

[0041] w is 1 or 2;

[0043] X is O, NOH, NOR, or NR, preferably O;

[0044] wherein R is independently at each occurrence hydrogen (H), C₁₋₂₂ alkyl, C₁₋₂₂ alkoxy, C₂₋₂₂ alkenyl, C₆₋₁₄ aryl, and C₆₋₂₂ alkyl-substituted aryl, and C₆₋₂₂ aralkyl where the C can be unsubstituted or substituted with heteroatoms such as oxygen (O), nitrogen (N), sulfur (S) or halogen;

[0046] A is O, NOH, NOR, NR or S, preferably O;

[0047] B is O, NOH, NOR, NR or S, preferably O or NR and most preferably O;

[0048] and where the polysiloxane or the silicone resin is bound to the (CR₂)_(r) (Formula IX, X, XII, and XIII), (CR₂)_(v) (Formula XI and XIV), or (CR₂)_(w) (Formula XV). Any of the linker structures shown in Formulas (IX) through (XV) can also be interrupted with cycloaliphatic rings or aromatic rings. Substituents on the phenyl group of formulas (XII), (XIII), (XIV), and (XV) may be present at any free valence site. The polysiloxane or silicone resin may or may not contain other functionalities by substitution at silicon atoms either the same as or distinct from those bound to the linking groups described above, such as amine-, polyether-, alkyl-, or heteroalkyl-containing groups.

[0049] The linker is typically derived from a polysiloxane or silicone resin bound linker precursor which comprises a linker bound to a leaving group (L). Illustrative leaving groups include halides such as chloride, bromide and iodide; tosylate, mesylate, phosphate; cyclic leaving groups (that is, those in which the leaving group remains bound in the linker) such as epoxy or other cyclic leaving group containing at least one heteroatom; and other leaving groups known to those skilled in the art. Preferred leaving groups are bromide, chloride, and iodide. In synthesis, the leaving group is replaced by a molecular hook, so that the linker becomes bound to a molecular hook.

[0050] The method for making the silicone compositions of the present invention includes combining a molecular hook, a polysiloxane or silicone resin, and a linker. The sequence of addition can be varied, for example, the linker and the molecular hook can be combined and this combination can be sequentially combined with a polysiloxane or a silicone resin. Preferably, the linker is combined with a polysiloxane or silicone resin and the combination is sequentially combined with the molecular hook.

[0051] Silicone compositions of the present invention which include at least one polysiloxane or silicone resin, at least one linker, and at least one molecular hook typically impart cosmetic and other durable benefits in products such as hair care products, but also including, textile care products, cosmetic products, oral care products, and animal care products. A particular advantage of the present invention is that many of the described linkers provide solubility, in consumer relevant media, to the silicone composition as well as the potential for additional hair care benefits which may or may not be typically associated with the functional groups of the linker. In particular, the molecular hook of the present invention is thermally and hydrolytically stable.

[0052] In hair care applications, the silicone compositions can be delivered to the hair in any appropriate formulation, for example, water or water and alcohol mixtures which can contain in a range between about 1% by weight and about 99% by weight alcohol based on the total formulation.
